| ithd THD o THDi: distorsión harmónica total Explanation: Tengo entendido que «THD» y «THDi» son términos equivalentes, no hay diferencia entre uno y otro. https://docplayer.es/79174007-Instalacion-funcionamiento-y-mantenimiento.html https://books.google.es/books?id=MDqtBQAAQBAJ&pg=PA502&lpg=PA502&dq=iTHD+espa%C3%B1ol+input&source=bl&ots=nS2ylOGa5y&sig=ACfU3U3omtSEUUqwcBk |

| ithd Input Total Harmonic Distortion/distorsión armónica total en/de la corriente de entrada Explanation: I am no expert in this area, but my research shows that “iTHD” has a distinctive meaning, Input Total Harmonic Distortion, and is not exactly the same as THD. The “i” stands for “input” referring to “input current”, “corriente de entrada”. As far as I know, the usual expression in Spanish is “tasa de distorsión armónica total”, but in this case referred specifically to input current (iTHD) and calculated in percentages, as shown in your own example (“Less than 5% iTHD”). https://www.satec-global.com/sites/default/files/Application... In order to enable analysis of the harmonic distortion, the parameter THD, which stands for Total Harmonics Distortion, is defined as [maths formula]. There are two different THD values for the voltage (THDv) and current (THDi). https://cisar.es/wp-content/uploads/2015/07/manual-tecnico-c... ¿Qué es la tasa de distorsión armónica (Thd)? (…) La Thd (Total harmonic distorsion), o tasa de distorsión armónica, es una forma de cuantificar numéricamente los armónicos existentes en un determinado punto de medida. En Europa se utiliza el Thd referenciado respecto a h1, la onda fundamental (f) (50Hz) de intensidad teórica calculada según potencia. La ThdI (%) es la distorsión de la corriente y la ThdU (%) es la distorsión referida a la tensión. La ThdI (%) se genera por la no linealidad de la carga, mientras que la ThdU se genera por la fuente como resultado de una corriente muy distorsionada. A partir de las corrientes eficaces (rms) de los diferentes armónicos, además de la fundamental: a) se calcula el ThdI (%) general b) se calcula el Ihn (%) para cada uno de los armónicos ( n = 3,5,7,…) en relación a la fundamental. http://www.seselectricsales.com/Controlled Power/HV.pdf Input Harmonics:<10% ITHD (Input Total Harmonic Distortion) https://www.uv.es/emaset/iep00/temas/IEP5-0607.pdf TEMA 5: Efectos de los Rectificadores sobre la red de alimentación (…) En toda esta normativa, se deduce que no se requieren equipos con una distorsión armónica total pequeña para la corriente de entrada (ITHD), sino un cumplimiento individual de los límites para cada armónico. However, a fact is that you find both the expressions “iTHD” and “THDI”. I believe they both mean the same, but I am not totally sure. Please see here: https://www.researchgate.net/publication/287406557_Multi-par... Multi-parameter mathematical model for determination of PC cluster total harmonic distortion of input current Purpose - Low power devices with switched-mode power supply represent harmonic generating apparatus in widespread use nowadays. The influence of personal computers (PCs), which affect the supply voltage, is considered. Harmonic level due to simultaneous PC operation is quantified by the total harmonic distortion of input current (THDI). |
